# nomad-csi

Nomad CSI storage for i80.dk — democratic-csi + NFS on int.i80.dk.

## Architecture

- **NFS server**: `int.i80.dk` exports `/opt/csi-volumes` to 192.168.15.0/24
- **CSI driver**: [democratic-csi](https://github.com/democratic-csi/democratic-csi) v1.9.0
- **Plugin ID**: `org.democratic-csi.nfs`

## Deploy

```bash
# One-time: deploy CSI controller + node plugin
nomad job run csi/controller.nomad
nomad job run csi/node.nomad

# Verify
nomad plugin status org.democratic-csi.nfs
```

## Create a volume

```bash
# Edit csi/volumes/example.hcl with your id/name/size, then:
nomad volume create csi/volumes/my-volume.hcl

# Volumes are persistent — only deleted explicitly:
nomad volume delete my-volume-id
```

## Use in a job

```hcl
volume "data" {
  type            = "csi"
  source          = "my-volume-id"
  access_mode     = "single-node-writer"
  attachment_mode = "file-system"
}

# ...in the task:
volume_mount {
  volume      = "data"
  destination = "/data"
}
```

## Expanding to all workers

When ready, update `csi/node.nomad`:
- Change `type = "service"` → `type = "system"`
- Remove the `constraint` block

Workers need `nfs-common` installed (via Ansible `storage.yml` playbook).
